Eight hours of sleep a day? The survey shows the best time for seniors and middle-aged people – small business is big business

The Sleep pattern We always ask that eight hours is the best. However, as we age, that number may change. Says one Study Conducted by the University of Cambridge and the University of Futan, it defines seven hours Sleep Suitable for middle aged and elderly.

Researchers from China and the United Kingdom studied data from 500,000 adults aged 38 to 73 from a bank of biological samples, Biopank. Participants were asked about their sleep patterns, mental health and well-being and participated in a series of cognitive tests. Report.

The team found that sleep duration – adequate and excessive – was associated with impaired cognitive performance. These include negative effects on processing speed, visual focus, memory and problem solving. Seven hours of sleep a night is the best sleep for cognitive performance, but also for good mental health – people reported more symptoms of anxiety and depression and worsened general well-being if they reported longer or less sleep.

One possible reason for the link between insufficient sleep and cognitive decline is the slow wave – the disruption of “deep” sleep. This type of sleep disorder has been shown to have an association with memory synthesis and amyloid accumulation – an important protein that, if misdiagnosed, can cause “problems” in the brain that are characteristic of certain types of dementia.

“A good night’s sleep is very important at all stages of life, but especially as we age. Finding ways to improve sleep in the elderly can help them maintain good mental health and well-being and prevent cognitive decline, especially in patients with mental disorders and dementia, “said Barbara Sahakian, professor of psychology at the University of Cambridge.
